D - Very distinct, this smells better than it tastes. The cask aging has had a huge impact on this beer mostly in the form of wine flavors, with little contribution from the bourbon. The oak brings out a lot of the acrid flavor inherent in the brown malt of the base beer. The barrel funk clashes a bit with the overall character of the base beer. This was an interesting experiment, but I can't say I'm upset that I won't have the chance to have it again.
